|Thanks. Unfortunately, I don't have time to delve into the code,

Well if i recall the situation then that GNU library which is now
linked into the build provides a function that actually offers
wcwidth() specifically for UTF-8, which is what groff would need.
Even if setlocale() has never been called that is, or called with
"C". I have reported this in 2014 i think, unfortunately i still
have no running fork.
